Abstract

The utility model relates to a low position venous transfusion device which is composed of an outer housing 1, a static pressure chamber 2, a soleplate 3, a corrugated tube 4, a cover plate 5, a matching block 6, a guide rod 7, a stationary shaft 8, a medicinal bottle rack 9, a medicinal bottle 10, a transfusion tube 11, an exhaust tube 12, a through hole 13, etc. The utility model is characterized in that the utility model does not use a transfusion rack, and can generate static pressure needed by venous transfusion, that is, physic liquor at low positions can also carry out venous transfusion.

Description

The low-position transfusion device

This utility model is a kind of medical apparatus and instruments, promptly a kind of low-position transfusion device.

In medical procedure, often need the patient is infused, promptly liquid preparation or blood plasma are imported human body by blood vessel.The infusion method of using always is at present, and medicinal liquid or blood plasma are suspended on eminence, utilizes the pressure reduction that highly produces that it is imported blood vessel.This mode needs a higher drip stand, when condition is relatively poor, for example during the war years, under some state of emergency, just is difficult to find drip stand sometimes.Particularly when the patient needs to go to toilet in the middle of transfusion, then need medical liquid container be held high and accompany and serve by the special messenger, very inconvenient.When transfusion finishes,, then can produce adverse consequences as the untimely pin that pulls out.Therefore, existing infusion techn is badly in need of improving.

The purpose of this utility model is that development a kind ofly can produce the required static pressure of venous transfusion without drip stand, and promptly medicinal liquid still can carry out the transfusion device of venous transfusion in lower position.

Above-mentioned purpose is realized by following technical scheme: develop a kind of low-position transfusion device, this transfusion device has a plenum chamber, and plenum chamber is made of base plate and highly compressible corrugated tube and cover plate.Base plate is provided with through hole, and exhaustor is housed on the through hole, and exhaustor one end is connecting the needle tubing that can insert in the infusion bottle.Around plenum chamber, be provided with upper cover plate and match, can make cover plate in the process of rising and falling up and down with the locating part of base plate keeping parallelism.On the cover board face is provided with the plane of placing balancing weight.During use, the needle tubing of exhaustor one end is inserted infusion vessel, under the pressure of balancing weight, plenum chamber dwindles, and imports gases at high pressure in infusion bottle, thereby provides static pressure for transfusion.

Said locating part can be two two guide rods that through hole is slidingly fitted with cover plate.

A medicine bottle fixed mount can be connected outside the said plenum chamber.

Also be provided with the cover plate stop on the said plenum chamber guide rod.

The intravenous transfusion device that adopts such scheme to make, without drip stand, medicine bottle still can be infused in lower position.Allow the patient to carry walking during transfusion, carry out the activity of some necessity.When medicinal liquid is totally lost when maybe needing to end transfusion,, thereby can avoid the accident that occurs because of untimely withdrawal of needle as long as block cover plate.This device is very suitable for using under situations such as relatively poor area of condition and military first aid.

Introduce two kinds of embodiment below in conjunction with accompanying drawing:

Fig. 1 is the front view of first kind of embodiment, and Fig. 2 is its vertical view.

Fig. 3 is the front view of second kind of embodiment.

First kind of embodiment:

Among Fig. 1-2 as seen, shell 1, base plate 2, plenum chamber 3, corrugated tube 4, cover plate 5, balancing weight 6, guide rod 7, fixed axis 8, bottle rack 9, medicine bottle 10, tube for transfusion 11, exhaustor 12, through hole 13, plate 14.

As shown in the figure, this transfusion device has a box-type shell 1, and the shell front side face is a kind of openable plate 14.Be provided with a plenum chamber 3 in the case, open a through hole 13 on the plenum chamber base plate 2, pick out an exhaustor 12, adorn a corrugated tube 4 on the base plate, establish cover plate 5 above, can place balancing weight 6 on the cover plate 5, balancing weight 6 has big or small polylith, can increase and decrease as requested.Balancing weight 6 middle parts are provided with mesopore, are provided with fixed axis 8 on cover plate 5, and balancing weight 6 can be by the mesopore string on fixed axis 8.In the plenum chamber both sides, erect two guide rods, cover plate 5 string in the above, thereby guaranteeing that cover plate is parallel with base plate rises and falls.On guide rod, stop is housed, use up when maybe needing to end transfusion at medicinal liquid, block cover plate and get final product.Opposite side in case is provided with bottle rack 9, and medicine bottle 10 can be inserted on the frame, also is inserted with tube for transfusion 11 infusion sets such as grade on the medicine bottle mouth, and the needle tubing of exhaustor 12 1 ends inserts medicine bottle.Under balancing weight 6 compressings, the corrugated tube folds shorten, the plenum chamber volume diminishes, and air is pressed towards in the medicine bottle, thereby by liquid level medicinal liquid is pressed to the human vein blood vessel by tube for transfusion.

Second kind of embodiment:

As shown in Figure 3, when medicinal liquid is packed flexible package into, medicinal liquid packaging bag 15 can be placed directly in above the plenum chamber cover plate 5, add a cover again pull with balancing weight be pressed in pack above, so just can infuse.In order to prevent the air admission tube for transfusion in the medicinal liquid packaging bag, can establish a limited block 16, the extreme lower position of limit compression.

Claims

1, a kind of low-position transfusion device, it is characterized in that: this transfusion device has a plenum chamber (3), plenum chamber (3) is by base plate (2) and highly compressible corrugated tube (4) and cover plate (5) formation, base plate (2) is provided with through hole (13), exhaustor (12) is housed on the through hole (13), exhaustor (12) one ends are connecting the needle tubing that can insert in the infusion bottle, at plenum chamber (3) on every side, be provided with upper cover plate and match, can make cover plate (5) in the process of rising and falling up and down with the locating part of base plate (3) keeping parallelism, on cover plate (5), be provided with the plane of placing balancing weight (6), under the pressure of balancing weight (6), collapsible the dwindling of plenum chamber (3), thus static pressure provided for transfusion.
